The new range Coloration Gloss Dia Light – L’Oréal Professionnel establishes itself as the essential reference for acid-based ammonia-free colorations, completely rethought to offer next-generation professional performance. Formulated with hyaluronic acid, a central innovation highlighted in the presentation document, it acts as a true strengthening treatment capable of instantly combating dryness, one of the first visible signs of hair sensitivity. Thanks to the Acidic Gloss technology and the acidic cocoon tech integrated into this renovation, Dia Light envelops the fiber to preserve the integrity of the cortex, reduce breakage after bleaching, and intensely enhance the color. The instrumental tests communicated in the PDF show a shine doubled and a color 82% more glossy, an exceptional result that distinguishes this renovated range from the previous Dia Light. Suitable for all types of colored, highlighted, or sensitized hair, it becomes the ideal professional tool for executing custom glazing, gloss, or refresh services. With its 76 new shades combined with the already known Dia Activators for colorists, the palette aims to be wider, more precise, and more modular than ever, allowing for ultra-modern cool highlights as well as sophisticated warm tones, always with a uniform and natural finish. The format is also evolving: the tubes now contain 60 ml, offering 20% more product for a more advantageous price per milliliter, as specified in the technical data of the PDF. This improvement comes with an optimized texture that is easy to apply and rinse, providing a smooth and comfortable professional experience. L’Oréal Professionnel's ammonia-free gloss coloration thus continues to solidify its status as a leader, enhanced by this new formulation that combines deep care, mirror shine, and optimal hold. Ideal for intensifying color, neutralizing unwanted reflections, reviving dull lengths, or enhancing a lightening, Dia Light offers an ultra-cosmetic result, soft to the touch and luminous, perfectly aligned with the current expectations of both salons and clients. With its intensive moisturizing power derived from hyaluronic acid and its ability to reveal a long-lasting gloss, it represents the perfect professional solution for anyone seeking a shiny, uniform, and fiber-respectful color. With this new generation of Dia Light, L’Oréal Professionnel offers an expert semi-permanent coloration that is focused on care, ready to become a staple in technical routines in salons as well as in professional home care routines.
